Q: If I plant a Alberta spruce that has spider mites on
it, and can't see them until the damage. Can those same spider mites get on
my other evergreen trees? ie. Cedar, and/ or Leyland cypress trees?
If you decide to plant the
Alberta spruces, I recommend you initiate a spider mite preventative control
program for ALL the susceptible evergreens in the yard, or at least the ones
near the spruces.
If the spider mite population gets out of hand, you'll
have a difficult time regaining control.
